What is Chrome Plated Hollow Bar & chrome plated od tubing?
Chrome plated hollow bar is is known as chrome plated OD tubing also, it is a very important and popular material for producing hydraulic piston rods and Linear shafts in various machines. The biggest advantage of chrome plated hollow bar than normal chrome plated bar is that the unit weight is light, people can greatly reduce the weight of the hydraulic piston rod, when design the safety hydraulic cylinders.
Chrome plated hollow bar are produced from hot rolled or cold drawn seamless tubes with outer diameter ground, polished and electro-plated with a certain thickness of chrome plating.
